Abstract |
Asynchronous protocols exhibit various noise robustness
and when used in GALS NoC links, they can directly affect the
signal integrity. In this paper we study the noise robustness of
two well-known asynchronous protocols, namely Dual-Rail
(DRP) and Bundled-Data (BDP) in the GALS NoC links, and
subsequently confirm our claims through simulations. We
apply an enhanced version of BDP and DRP to 32/64 parallel
line links, show results in terms of noise robustness using
global interconnect features, specified in the ITRS roadmap
for 32nm technology.
The simulation results for two thousand random generated
inputs show that the number and the amplitude of noise
glitches over ‘0’ state lines as well as the required threshold
voltage needed for avoiding errors in BDP link are much
lower than in DRP's. Therefore, BDP links can present better
signal integrity features and have less overhead compared to
DRP's, employing only some simple noise reduction
techniques and more timing adjustment effort. |
